At the moment, the audio shortcode only allows four attributes, src
, loop
, autoplay
and preload
. When you upload an audio file however, it comes with pretty useful meta data such as the album art, artist, year and so on which would be great if it could be displayed as well. I've been looking for a way to extend the audio shortcode so that the meta data can be included in the shortcode as well.
So far I have stumbled across shortcode_atts_{$shortcode}
which can be used to filter existing shortcodes, but apparently one can only filter existing attributes, not add new ones. I'm not looking to create a new shortcode btw, but add to or extend the existing one, so a user doesn't have to use a new shortcode to get this effect. Is there anyway one can achieve this? I'm grateful for any pointers.
